- Draw a stepwise mechanism for the conversion of lactone A to ester Busing HCl in ethanol. B is converted in one step to ethyl chrysanthemate,a useful intermediate in the synthesis of a variety of pyrethrins, naturally occurring insecticides with three-membered rings that are isolated fromchrysanthemumsarrow_forwardDraw a stepwise mechanism for the formation of A from an alcohol and acid chloride. A was converted in one step to blattellaquinone, the sex pheromone of the female German cockroach Blattella germanica.arrow_forwardOctinoxate is an unsaturated ester used as an active ingredient in sunscreens. (a) What carbonyl compounds are needed to synthesize this compound using a condensation reaction? (b) Devise a synthesis of octinoxate from the given organic starting materials and any other needed reagents.arrow_forward
- (a) Give an acceptable name for compound A. (b) Draw the organic products formed when A is treated with each reagent: [1] H3O+; [2] −OH, H2O; [3] CH3CH2CH2MgBr (excess), then H2O; [4] LiAlH4, then H2O.arrow_forwardDraw a stepwise mechanism for the sulfonation of an alkyl benzene such as A to form a substituted benzenesulfonic acid B. Treatment of B with base forms a sodium salt C that can be used as a synthetic detergent to clean away dirt (see Problem 3.22).arrow_forwardDraw a stepwise mechanism for the conversion of lactone A to ester B using HCl in ethanol. B is converted in one step to ethyl chrysanthemate, a useful intermediate in the synthesis of a variety of pyrethrins, naturally occurring insecticides with three-membered rings that are isolated from chrysanthemums.arrow_forward
- Draw a stepwise mechanism for the following reaction that forms ether D. D can be converted to the antidepressant fluoxetine (trade name Prozac) in a single step.arrow_forwardDraw a stepwise mechanism for the following reaction that forms ether D. D can be converted to the antidepressant uoxetine (trade name Prozac) in a single step.arrow_forwardOne synthesis of the cholesterol-lowering drug atorvastatin involves the construction of the pyrrole by reaction of diketone X with amine Y. Draw a stepwise mechanism for this reaction.arrow_forward
